Comment 1 for bug 24572

I agree, but I don't think it should be a frontend to all of /e/n/i. I think it
should use something like update-grub's begin/end comments so that the admin
doesn't change anything important by accident.

For example, /e/n/i could look like:

auto lo
iface lo inet loopback

### BEGIN GNOME-NETWORK-ADMIN SECTION ###
# Do not change anything between the above line and
# "END GNOME-NEWTORK-ADMIN SECTION", use gnome-network-admin instead

<stuff>

### END GNOME-NETWORK-ADMIN SECTION ###

This could keep lo from showing up in g-n-a. If this is done, I think the best
way to use it by default would be to put "fake" interfaces that the end user
doesn't care about (e.g. lo, hotplug) in the static part and put "real"
interfaces into the g-n-a part.
